Didn't she say whoever's behind
this might be playing games?

Maybe that's exactly
what she's doing.

Lynn Zobrist

they all have scars
on their temples.

Maybe the other victims
have suffered

some serious
psychiatric problems, too.

I spent some time in a facility.

Most of one body.

Left leg's been severed

We got different

Look.

There's still some
skin on this fellow,

JACK:
She's nothing but bone.

Maybe the coyotes found
her especially tasty?

"She"? "Her"? How can you tell?

Well, just a guess based
on the cranial vault.

FOLSOM:
Forehead angle is vertical,

not receding,

and the supraorbital
margin is sharp, suggests

sex is likely female.

Late teens, early 20s.

You okay?

Yeah.

Okay, jackpot.

Gentleman
with the missing leg is...

Harrison Cantwell.

Okay if we roll him?

Yeah, go ahead.

Listen, Cantwell's
fingers were curled inside

the skull's
occipital opening.

And rigor set in, just...
(clicks)

He was locked on tight.

Yeah.

Like an action figure
with a kung fu grip.

So, he holds on all
the way downriver,

but...

RAJAN: Wondering
where he came from?
Yeah.

He could have floated
quite a ways.

W-We got a heavy
rain last night.

This watershed is very prone
to flash-flooding,

especially in
the middle of this

drought season
that we're having.

ROBY:
Is that right?

My-my point is,

he didn't get killed at
Flash in the Pan Tours and...

Well, maybe she can

pass that along to any

reporters who
might be wondering.

CHAVEZ:
Okay, Mr. Jakes. Thanks.

You can go.

All right, so I
did some googling

on our victim
Harrison Cantwell.

Apparently, he was some sort of

amateur archaeologist
turned author.

Well liked, did a lot
of philanthropic work

for museums around the world.

Semi-famous in nerdy circles.

Oi. I've heard of him.

Yeah.

Now, he's from New York,

but he's got
an honorary seat

on the board of the Natural
History Museum of Clark County.

Maybe that's what
brought him out here?

RAJAN: Well, I was
heading there next

anyway. They have the equipment

I need to
carbon-date the skull.

So, you-- the body
and the murder weapon.

You-- the ancient skull.

And another thing.
Come here a minute.

That 419 this morning?
Mm-hmm.

In the dead
man's trunk

was a card written
in silver ink.

"Keep your secrets.
Cull the rotten fruit"?

It seems like

he was sent to kill
this young woman

and she wasn't having it.

Then this would-be victim,

she could be another link
in the chain.

I need to talk to her
as soon as possible. No.

We need to walk and chew gum
at the same time.

I will stay on your
silver ink case

'cause I need
your expertise on this

ancient skull business.

Thank you.

All right, y'all.
Come on.

QADIRI: More than an author.
He was so charitable.

So kind. Like a brother to
all of us here at the museum.

Are you sure it's him?

Wow.

You all seem surprised.

But from what we can tell,
he must've been missing

for close
to two months.

Cantwell wasn't a traditional
scientist per se,

but he was passionate.

He immersed himself in research.

QADIRI: Before his last
three books, he went off-grid.

Five, six months.

Embedding, searching.

No one ever thought
anything of it.

Zimbabwe, the Yucatán.

This last time,
he was looking for

Clovis artifacts

in the Basin and Range.

Well, he might have found more
than just artifacts.

Um, there was a Clovis point,

a murder weapon that
we took back to the lab.

But there was
something else.

Here, have a look
for yourself.

What in the world?

Tad, run and get
my hand lenses.

Do you think it's possible?

That this is a Clovis skull?

It-it would be
the find of the decade.

QADIRI:
Wear on the bone,

the teeth,
it certainly could be.

MacARTHUR:
We have so few

links to the oldest humans
to walk on this continent.

Someone has to
write this up.

It should really be you.

Perhaps Tad can assist.

For now, I'm
assisting. We need it.

It's part of a homicide investigation.

Our lab can handle
tool mark analysis

on the Clovis
point, but

do you happen to have

a, um, accelerator
mass spectrometer

for carbon-14 dating?

Mm-hmm.

Do you mind if I play with it?

We're trying to find out
if she and your friend

were killed by
the same weapon.

beautiful this morning.

Sun was shining. Here?

I mean...

the lab is
great. There.

But, uh...

field work is

11 points of minutia
on the Clovis point.

11 matching points

on the defect
in the skull.

They-they measure out

perfectly.

Yeah, it's a match. Yeah.

Looks like there's some little
fragments from the arrowhead

that were broken off
in the skull itself.

No weathering on
the broken edges

means it was probably
pulled out recently.

(yells)

Like,
maybe right before the attack.

What if this is what
they're fighting about?

I mean, it could be, they know
the value of these artifacts,

I mean, if they're as old
as Allie thinks they are.

Oh, they are.

Radiocarbon dating
says this skull

is 12,245 years old.

Give or take.

We're talking 10,000 BC? Wow.

That's older than agriculture.

RAJAN:
I know.

So, Harrison Cantwell
managed to find a skull

that had been hidden from
humanity for 12,000 years.

Wherever he found it, that's
got to be our crime scene.

Yeah, it's taken since
the end of the Ice Age

for someone to find it.

Yeah, well, I'm sure we'll have
it sorted by lunchtime tomorrow.

Okay, okay. Okay,
okay, okay, goodbye, Sonya.

No, you are. Mom agrees.

Yeah, kisses.

Hey, Jack, is your
sister out of town?

She's in London
presenting a paper.

"Sudden Death and
Fibromuscular Dysplasia

of the Mesenteric
Arteries."

RAJAN:
I've seen her slides.

They're really funny.

You knew about this?
Yeah.

She asked me for kebab recommendations.

JACK:
Don't worry.

We FaceTimed our way through
a very thorough intake.

Mm.

Ready for the highlights?

Our victim was stabbed

five times using
a stone object.

Probably held in the hands,
not a spear.

The wounds are
too shallow.

The final stab into his eye
isn't what killed him.

This wound, in the
inferoanterior cardiac muscle

near the right ventricle, caused
a hemorrhage into the torso.

(screams)

Broken bones in
the arms and jaw

suggest fistfight.

Broken carpals and metacarpals.
He fought back.

And what about the leg?

Uh, leg.

Jack?
Ah! (laughs)

Right. If you look at the
position of the cartilage,

definitely postmortem.

My guess is some kind of animal,

like a coyote, tugged at it

till it was torn off.

What about this?

Huh.

Looks like... sand?

Maybe? Stuck to
the hardened earwax?

RAJAN:
There's quite a bit of it,

especially...

given the advanced
state of decomposition.

Meaning what?

RAJAN:
I don't know yet.

But this kind of
eluvium might tell us

where Cantwell was
before he was killed.

Molly, you know you
don't believe that.

And neither do I.

Honey...

You need to be put

in protective custody.
I can't.

I don't... I don't want to.
The man who came here

to hurt you,

he was sent here by someone.

Someone who also
sent you a dossier.

And a card with
silver ink, Molly.

Silver ink.

Silver ink. I don't know.

I don't know, I'm scared!

We all get scared sometimes.

But the person who
send you that dossier

and that card with
the silver ink,

they left something on it.

I can find it...

if you let me.

I've been so tired.

Silver ink. Silver ink.

I'm gonna trust you.

Find him, please.

Come here.

Hey, Detective, you're back.

We need to speak
to Dr. Qadiri.

I-I think
she's in her office.

There-there's nothing
wrong, is there?

I don't know yet.

Would you mind
taking us back?

Of course.
Uh, right this way.

That's strange. Uh...

This-this door is

never locked
during business hours.

But, um, here.

Used to be my office, I can...

let you in
no problem.

People are in and out
of here for supplies

all the time.

Hey, this has Rose Cantwell's
name on the return address.

And it's postmarked
after Harrison died.

Did Rose mention that she was
friendly with Dr. Qadiri?

Uh-uh.

RAJAN:
Huh.

It's open.

RAJAN:
By the looks of it...

she sent
Qadiri some...

of Harrison's notes.

I'm also seeing what looks like
two sets of handwriting.

You think Dr. Qadiri
and Rose were planning on

getting rich
off his big find?

I mean, it was brand-new dig
site, it was barely developed.

I doubt the killer
counted on Cantwell

making a run for it after
being mortally wounded.

If they had hopes of
taking credit for the find,

they might've been waiting
for him to pop up.

What are the odds?
If there's one thing

I've learned
since I moved to Vegas:

don't put anything
past anybody.

Especially when it
comes to getting rich.

See what you can
get off of that.

FOLSOM:
Hey, guys.

So, Max took a crack at
finding DNA in that blood

that we found
at the scene.

No dice.

Hydrogen peroxide
stays undefeated.

We're having better luck here.

Fingerprints from
both Rose Cantwell

and Dr. Laura Qadiri on
Harrison Cantwell's notes.

Both of them were
working together,

and yet both of them
failed to mention that.

FOLSOM:
Time for a little
dueling banjos.

Maybe both of them ought
to come have a chat about it.

I'd like to see them deny it.

ROSE:
No, you're right.

Dr. Qadiri and I were
working together.

We started a few months
before Harrison was killed.

Rose is a brilliant
prose stylist.

She was pushing Harrison to
the next level of his career.

ROSE:
Laura brought extensive archaeological

expertise and credibility,
which Harrison

was frankly lacking.

QADIRI:
Harrison, Rose and I had a deal.

I'd help research the Cantwells'
book, write the foreword.

In exchange, I could publish
anything Harrison found

in the academic press,
as lead author.

Well, why didn't you mention
this earlier?

It's not like we're
hiding anything.

All of this had
Harrison's blessing.

ROSE: It didn't seem
particularly relevant

to your investigation.

We found Harrison's
satellite phone.

And the last call he made
might've been the day he died.

Can you tell us where
you were on January 9th

at 1:30
in the afternoon?

FOLSOM:
Where were you...

on January 9th at around
1:30 in the afternoon?

CHAVEZ:
He had just made the find

of a lifetime.

He called it in.

And one of you
killed him for it.

QADIRI: Wait,
wait, wait, stop.

Just... Just hold on.

January 9th? I was
traveling that weekend.

A lot of people saw us.

Saw who?

CHAVEZ:
You and Dr. Qadiri
were both in Illinois?

ROSE:
In point of fact,

we were together.

I hate to say it, but
I-I think our theory

is kind of
falling apart.

Oh, no, it's really
falling apart.

Laura and I were in Chicago
to speak with a publisher.

The meeting

Do you think that's

Right after he

Any of y'all want to call

FOLSOM:
Come on, boss.

This is our chance to
drink mediocre coffee

at 2:00 in the morning.
Yeah, was your chance.

I can't stop thinking about
Cantwell's last phone call.

I mean, two minutes
and eight seconds.

Someone at the museum answered,

talked to him and turned him
into a hotel for tarantulas.

FOLSOM: Well,
there had to be

a lot of young and
hungry archaeologists

at the museum who
would do anything

to lay claim to the
discovery he made, right?

Logan MacArthur said everyone
had access to the office

where the call came in.

It was never
locked, so

tying to someone specific
is gonna be tricky.

Actually...

there might be someone
we can tie to the crime scene.

Do we still have that
blood sample from the rib?

The one that killer cleaned up?
FOLSOM: Oh, yeah.

We got lots of blood.

No DNA to speak of, though.
RAJAN: If I'm right,

we don't need DNA.

(chuckles)

Blood.
Thank you.

Wright stain.

Well, red blood cells
look normal.

RAJAN:
These are different kinds
of white blood cells:

you've got neutrophils,
lymphocytes and monocytes...

There are four different types,

but we're only interested
in one:

the basophils.

FOLSMOM:
And basophils
are the markers

for this disease?

Mm-hmm. And when there
are no basophils,

there are a lack of histamines.

FOLSOM:
I guess if all
this blood work

helps put the killer
behind bars,

at least they get
a free diagnosis out of it.

RAJAN:
I'm not seeing

any, are you?
Nope.

The person who left their
blood at the crime scene,

all their histamines were stuck
to the underside of their skin,

which means...

Our man has cold urticaria.

Our man? We got him?

We got him.

There you go,
Mr. MacArthur,

nice and cold.

(clears throat)

I want to help you all
in any way that I can,

but... (chuckles)

...frankly, I-I'm not
sure why I'm here.

CHAVEZ:
On the day he died,

your friend Harrison Cantwell
made a phone call.

The last one he'd ever make.
To Dr. Qadiri's office.

Your old office.
Now, you're

in there all the time, right?

You admitted it yourself.

I'm not sure what
you're driving at, but...

I didn't speak to Harrison.

Yeah, you did.

Your pal Harrison,
he told you about his discovery.

A career-making find.

So you raced out there
and found out it was true.

A man who was not a scientist

had discovered something

you never could.

And he was on his way
into the history books.

You argued. You fought.

(grunting)

You got injured,

your resentment boiled over,

and you stabbed him.

(Cantwell screaming)

But you were too hurt to follow.

How am I doing so far?

You want
to show us your scar

where you got impaled
on that rib?

I loved Harrison.

Uh, I wouldn't hurt a bug,

l-let alone a-a great thinker,

a-a great friend.

You don't have any proof
of any of this.

Uh-oh.
(raspy exhale)

What's-what's that there?

N-nothing. Just a nettle rash.

I-I get it sometimes,
because of cold.

ROBY:
I know.

Your "nettle rash" is actually
a minor immune disease

called cold urticaria.

If you say so.
CHAVEZ: Oh, we do say so.

That's actually how we know
you returned to the scene.

And cleaned the bones
with hydrogen peroxide.

I mean, that was very smart.

It was.

Because it took care
of all the DNA.

But it did not destroy
the blood cells,

or the telltale signs

of the disease
they're fighting.

Sir, the killer had
cold urticaria.

The same thing Ms. Rajan noticed
that you had back at the museum.

(laughs)

(crying):
I-I-I...

I didn't want any of this.

I-I was just upset.

He-he was going
to take credit.

It was all an accident.

I'm sorry, this is
about credit?
You wouldn't understand.

50 years I-I've worked.

I-I've never had a find

like that.

Harrison
w-would've never

found that site
if it were not for my help,

my museum's
resources.

He had his whole life
ahead of him.

He could've shared this.
He-he could've made

a hundred new discoveries.

No, he's not going to.

Not now.

Hands behind your back.

Stand up for me.

(jingling)

Poor gal got a spear
stuck in her craw.

(Roby laughs)
Yeah.

What's stuck in yours?

It's nothing.

You know what?

A few weeks ago,

you asked me
what was wrong.

And I told you.

Back in Miami,
when I first made detective,

I got a case.

16-year-old runaway,

disappeared from
a motel room in Opa-Locka.

A little keychain
like this was

the only thing left behind.

Until about a month later

we found her skull.

Just her skull.

I was green,
so I thought if I just

worked the case
hard enough...

(chuckles)

But that's not always
how it works.
Mm-mm.

It's a hard lesson.

I mean, we can't always
find the bad guys.

But her family...

Her family saw
you try, right?

That matters.

Only so much.

Only so much.

You go through Molly's dossier?
GILL: Yep, fully processed.

453 pages of

It was really interesting.

Not the what,

When I found
Lamont Moore's dossier,

it showed that he was being

electronic surveillance.

Molly's was different.

A few years ago,
she confessed to

But not to her diary,
not to police.
